A 30 foot ladder needs to reach 18 feet high against a building. What would the approximate angle of elevation be from the ground?

The angle of elevation is 36.87°

Step-by-step explanation:

We use the sine ratio to determine the angle of elevation, x.

The sine ratio is given as:

We substitute the opposite side, which is the height of the pole and the hypotenuse, which is the height of the ladder to get:

This implies that;

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
